Tri all whom L may concern: v

Be it known that I', HELEN A. BLANeHARma citizen of the United States,residingat Philadelphia, in'

the county of Philadelphia and State of Pennsylvdnia, have invented newand useful 'Improvementsin Hat- Sewing Machines, of which the followingis a specification.A

My invention relates to certain new and useful improveniente in sewingmachines making a common overedge' chain stitch with one thread aplurality of thread carriers; and it is designed primarily to sewsweat-bands into hats and onto astrap of linenor other material,hereinafter termed a reed, which hasI been i previously hzisted ontheinner edge of the h'at.

' toher 1901, ythe nischine'sewng reducing the cost oi i lthe finishedhat and resulting in a betterl fastening of Hcretofrethe sweatbands inhats have been sewed onto the busted strip by hand, and by, machinery,as ior instance by the mechanismvshown, described sind claimed in myformer patent No. dfdf'dated Octhe sweat-band to the basted strip of thehat. i The present invention-is an improvement on my aforesaid priorpatent and it .omprehends means `for supporting the hatwith its'attached or hosted reed relative to the band and then'attaching thesweat hand 'or leather to the eedby a sewing 'thread and a.

locking filament or thread, v vhichisA automatically fedY with the band,and which is mbved alternately substentially across the pitth describedby the lower sewing needle, and eoncatenating the sewing thread to forma series of interlocking loops certain of which are looped around thelocking filament or thread and others ockefl outoi sight in the seperatethread and thereby removed iroln the edge of the reed'.

M y invention further comprehends certain improvements in' the means bywhich a lockingthreador fils.- rnent is movedlsubstantially into and outof the range oi action of one of the sewing needles; in the means foractuating an oscillat'ng thread carrier or looper; in

the arm of 'the machin having a jointed or hinged section Iand lockingmeans therefor, and in certain other fer-.turcs which I'ywillhereinafter describe and claim.

In kthe accompanying drawing, l illustrate a machine o the type shown inmy said former patent, having the present improvements eppliedy thereto.

Fig. fi is asimilar" section ou the linee-4 of Fig. l. lFighis s .wcijoss-sec'tionon', y the line otli'ig. 1. Fig.;6 is a plan view of the y i1/nf lbthplatev andthe clevicegeT ltion' is given the lqoper through the mediumofalcsm derside o! the v one side of its pivotal connection.

thereon. Fig,Y 7 is a sectional view'oi the jointed end of the lnchinefirm. Figs. 8--9-10 il and 'lZ nrc details tobe referred to.

Referring howto said drawing for a more complete explanation o myinvention, A represents the machine arm, which is designed inbeappropriately' supported on or secured to a table a. This rm isprovided with two bearings a in which ismounted the main shaft B havingfixedw it a pulley b in'themsual manner.

-'On s bracket, A depending from the main arm A is fixed the cloth platee Io the machine and in line therewith, towards thelr left end, isp.movable support ai for the hat-rim and which supboyt iissuitbly held inplace by a set screw e4 or equivloiit means, to the channeled guide orblock a5 on the' curved -encl A of the' arm A, said curved end formingahorn and being jointed or pivo'taily connected to tlieferm A at thepoint 2 whereby it may here' and lowered about its point 2 to facilitatethe insertion antiremoval of the The stitch-forming mechanism includes;a i lower thread carrying sewingk needle n which is appropriately hatrelative to the cloth plate, as I will hereinafter v more fullydescribe. 1. v

secured to an, oscillatinand curved needle arm N piv oted on a stud' fn?rojectiV from thev machine arm and which arm N receivesoscillatory-motion about said stud from an eccentric n3 n the moin shitand :in eccentric strap n* connected 'to the arm h' at. a point at Thelower needle n. has ah thread-'engaging eye-and A operates inconjunction with en upper needle u having a. thread engaging notch orbarb. adapted-tengage and carry a thread through the goods'.,-Thioupperneedle which I will hereinafter refer toas the barb needle,is

which receives its movement from the main shaft B through the medium-ofan eccentric-pin disk U3 and connecting rod 1/3..A i t In addition tothe foregoing the stitch-forming devices include e. thread loopei twhich-:ts shown, is hinged to a rock shaft t, which extends to theright,

said looper'lbeing designed to have a combined oscilletory and ,abackward/and forward movement. This -suitablysecured toavertically'reciprhcal needle barge', i

looper il hinged at t to the rock shaft t', journaled in a bracket' t3oi the machine arm, said rock shaft being` given a vibratory motion bymeans oi' a earn groove'ZX madenin, the tsgeof a'disk D fixed to themairi'shsft B.

`it verticsl'mdtr shaft 'c ijoumaied ma 'bracket or hearing onthemachine' arm and carries at its upper .fend a roller which operates inthe cam'groove ,cj the D, thelower end of'said rod being connected to lsind or arm '3 projecting from the rock shaft t whereby the shaft isrocked in itsbeering and a rocking move-1 ment yisimp'rtedto thelooper.The oscillatory is designed to Snap into engagement with a notch orundercut recess in the hinged part oi the arm and thereby hol the hingedportion of the arm ina locked 'posi ron. Tp release .the hinge part ofthe ami, the pin 3,3' is pushed down until its lower end comes incontact with the free end of the spring plate 80 and thereby forces fthe catch of said plate out ofthe recess and allowsfthe "hinged-,endofthe arm to be lifted to remove the hat.

The locking thread is shown as passing over a suitable4 [v tensiondevice 36, through' the eye 9 of the arm S and acrossthe front of thecloth plate and back oi a tension 40, Fig. 2; and the sewing threadpasses over a tension device 3.5v and through guides 37-3'S 39 and theeye of the lower sewing needle, To the iront under- 1'5 side o thebclothplate is fixed a plate 4l having a yertical portion-42 with an openingin which a'portion oi the vfeed operates. Y

The inner portion of the plate ills provided with a vertical groove orchannel Li4 which stands inline with the upper needleand'gudes andreceives the point of thisneedle and thereby keeps the needle firm sothat the lowerthreadled needle may pass through the loop in formingthe-second stitch. The lower end oi the' groove or channel 44 is closedat opposite sides io form -a sheath and brace' i'or the point ottlieneedle, as shown in Fig. l2.' The presser foot 46 is also k'provided'with some' suitable form of guide, as 47, for the leather band.' fTliemachine .will be mounted in any usual or well known manner and willbosupplied withsuch com- ,30 plernentary accessories as may be necessaryfor the Iwork to be performed. f "j Having thus described my inventionwhat I claim as new and desire to secure by Letters Patent iszp 1. In asewing machine the combination oi'ra lthread- `3 5 carrying needle, areciprocal needle operating substantially opposite to tbe first needlesaid second reedle provided with a threadengaging notch, a threadcarrier adapted to' taltev a loop from the thread-carrying needle andpresent it to the notch of the other needle, complcmentary` mechan- 40ism for actuating the needles and the loopcr,A an oscillating membersupporting 'a iocking thread proximate o he 'needleaand means wherebythe locking thread le altermately moved to allow the thread-carryingneedle' to pass above and below the locking thread during successiveoper;

ations o1 the machine.

3. A sewing machine having in combination oppositely operating needlesone ot which la provided with an eye for a sewing thread, and the Aotherhas a threadengaging 6() notch, means Ier taking a loop of the sewingthread from the eye-needle and presenting said loop-to the notch of theother needle and moans for presenting a locking thread irst on one sideand then on the opposite side of the path of movement'oi the eye-needlewhereby the sewing thread is concatenated to form a series ofinterlocking loops cci'- tain oi' which are looped around thc lockingthreadand others iocked outof sight ln the separate thread.

'-i. ln a sewing machine the combination of stitch-forming mechanismincluding? oppositely operating needles one 1,"0 of which isprovidedvwith an eye and the other with a recess, and a thread carrieradapted'to take a loop from ther,
